This has the best overall construction of any honing guide we've seen. It is made of two solid turned brass bobbins, each fitted with a Delrin roller, running on solid stainless steel guide rods. A threaded rod through the center is used to tighten the bobbins to the side of your chisel using a solid brass knob.
Uniquely, you can mount the chisel under the guide bars, as well as above them. This simple innovation makes it possible to accurately hone very short chisels, very narrow chisels, and chisels with extremely long primary bevels. All are nearly impossible to hold in most other honing guides. And, because the rollers are outboard of the chisel, the jig will not rock as you hone.
Made primarily for chisels that are from 1/32 to 1-1/8" wide, the Standard Guide (pictured) is not generally for wide plane blades. The Long Guide can hold blades up to 2-5/8" wide, however. Made In Great Britain.
